大吉山钨矿选厂有运输胶带30余条,日运输量4000吨,年运量近100万吨,磨损很快,服务寿命短,因而维修频繁,影响生产。损坏的胶带原来一直采用热硫化粘接法修补。一米胶带需上胶2～3次才能补好,耗时16小时,若加上各种准备工作,则至少要过30小时甚至2～3天才能交付使用。有时还因固化时间不够,一投入运行就出现接口脱裂。此 Dajishan tungsten ore processing plant has more than 30 transport tape, daily transport volume 4000 tons, annual transport capacity of nearly 1 million tons, wear fast, short service life, thus frequent maintenance, affecting production. Damaged tape has always been hot curing adhesive repair. One meter tape to be glued 2 to 3 times to make up, took 16 hours, if coupled with a variety of preparations, then at least 30 hours or even 2 to 3 days to deliver.
